Subject: [dpdk-dev] [PATCH 2/2] net/mlx5: fix ASO age null context issue
Date: Wed, 12 May 2021 14:52:38 +0300 [thread overview]
Message-ID: <20210512115239.12783-3-jiaweiw@nvidia.com> (raw)
In-Reply-To: <20210512115239.12783-1-jiaweiw@nvidia.com>
The flow context in the rte_flow_action_age structure was set by user,
and reported by the MLX5 PMD while calling rte_flow_get_aged_flow API.
If the flow context was NULL while create ASO age action, while flow
aged, the PMD report the NULL context to user.
This patch adds the checking if context is NULL then return rte_flow
pointer to user, otherwise return the original flow context.
Fixes: f9bc5274a6f9 ("net/mlx5: allow age modes combination")
